Research suggests that oregano demonstrates anti-inflammatory properties in laboratory settings, with cell-based studies finding that oregano can suppress key inflammatory markers such as nitric oxide, TNF-α, and IL-8, and that these effects appear to survive heat-based preparation methods like those used in making tea. The available evidence comes primarily from in vitro studies and review articles rather than human clinical trials, and while findings are generally supportive for the laboratory context, researchers consistently caution that whether these effects translate meaningfully to the human body depends on how well the active compounds are absorbed and reach relevant tissues. One review noted that oregano's constituent compounds may also influence gut health indirectly by modulating bacteriophage activity, adding another potential pathway through which anti-inflammatory effects might operate. A notable limitation in the overall evidence base is the absence of rigorous human trials, and one case report raises a practical safety concern — that oregano infusions may interact with anticoagulant medications — underscoring that even traditionally used herbal preparations carry risks worth discussing with a healthcare provider.
